In short:

HSUPA is fastest
HSDPA is still fast
UMTS is fast-ish
EDGE is semi-fast
GPRS is pretty slow

You need both 900 and 1800 MHz GSM on a phone to get decent service in much of Europe. Adding 3G 2100 is good.

GSM stuff has backwards compatibility. If it supports one of the protocols on that list, it'll support everything below it. The only exception is EDGE; not all 3G phones support EDGE. (My Sony-Ericsson K610i doesn't, e.g., although my 2.5G Z310i does.)
